People around us appeared to be having afternoon tea with dessert or beers. We ordered beers, Leffe for Bob, De Koninck for me (Joe and Al had hot chocolate) and asked our waiter if they had some real food. He said, "Trust me, I will bring you something delicious."
He brought us a fabulous tray full of snack foods. It had wings, salami, cheese, egg rolls, olives, pickled onions and funky meatballs. There was more than enough for the four of us. The cost was about five euros apiece.
This is a great place to people watch both in the café and also on the Grote Markt.
